So I have the EPG collector working, and created a CMD file for the scheduler. I am aware that the collector will fail if WMC is running.

So what services do I need to stop / start to get the WMC to automatically restart after the EPG has run ?

I can stop ehRecvr service, run the EPG collector, then restart service, but WMC Live TV stays stalled unless I restart WMC.

WMC is configured to run on startup. It's for a dedicated HTPC.
